In this document, we describe a collaboration model used in a training program for in-service teachers of secondary mathematics. We briefly describe the curricular design of the program and focus on the methodological aspects that promote interdependent learning. We found that the program contributes to the learning of in-service teachers in relation to their planning practices in, for example, the use of curricular documents and their prediction of student errors.
